A 16-gram bullet moving at 1825 m/s plunges into 2.5 kg of paraffin wax. The wax was initially at 30°C. Assuming that all the bullet's energy heats the wax, what is its final temperature (in ºC)? Take the mechanical equivalent of heat to be 4 J/cal and the specific heat of wax to be 0.7 cal/g °C. Round your answer to the nearest 2 decimal places.
Homework Answers
Concept: here kinetic energy of the bullet will be equal to the
heat energy needed to raise the temperature of the wax

A 5.00-g lead bullet moving at 400 m/s penetrates a wood block and comes to rest inside the block. If half of its kinetic energy goes into heating the bullet, what is the bullet's change in temperature? The specific heat of lead is 128 J/ (kg*K).

Lend has a specific heat of 128 J/kg°C. A lead bullet is moving at 650 m/s. If the bullet is suddenly stopped so that all of its kinetic energy is converted into heat, determine the temperature that the lead bullet reached before it was stopped. Take the initial temperature of the bullet to be 30 °C.

A 3.00 g bullet moving at 115 m/s strikes a 50.0 g stationary wooden block and embeds itself in the block. The bullet is made of lead, and the specific heat of lead is 128 J/(kg · °C). Assume the thermal energy generated in the collision is equally distributed in the bullet and the block. (a) Calculate the rise of temperature (T) of the bullet if block is clamped in place so that it cannot move. (b) Calculate the rise...
